Brush



Patented llune 16, 1931 gfNlTl STATES PATENT Biwsig Application filed June 13,

This invention relates to improvements in brushes, brooms, and devices of similar character and nature, usable with or without a handle, and more particularly to devices or' this nature, in which the bristles are eiiectively supported and maintained substantially in their initial position while the device is in use.

rhis invention is designed to overcome defects and objections in a provision of a brush or device of like character having means which are simply and easily mountable therein for stitfening or supporting the bristles.

The invention also seeks to provide means i for stiiiening the bristles of a brush or the like, which means may be flexible or rigid, and mounted at any desired angle withl respect to thebristles. While some of the more salient features, if? characteristics, and advantages, of a machine embodying this invention have been above pointed out, others will become apparv ent from the following disclosures. m The invention includes these and other features of construction and combinations of parts hereinafter described, and shown in a preferred form in the drawings, as more particularly indicated by the claim.

On the drawings Figure l is a fragmentary end view in elevation of a device embodying principles of the present invention.

Figure 2 is a fragmentary transverse secnV tional view of the device shown in Figure l, @d Y looking in the same direction as in Figure 1.

Figure 3 is a fragmentary longitudinal sectional view taken substantially along line III-III of Figure 2. A Figure tis a reduced fragmentary lview 9 similar t0 Figure 2, showing a slightly different form of construction.

As shown in the drawings In the illustrated embodiment of this invention', there is shown a brush of the type commonly termed a! push brush, comprising a relatively rigid back or bristle holdingmember 1,'to which a handle 2 is secured in any desired manner, or imbedded therein as shown more clearly in Figure 2. Inthis instance, the back or bristle holding member l is pro- 1929. Serial No. 370,588.

vided; with a plurality of pockets or recesses 3 in the under side thereof' in which bristles tare secured in any desired manner, as for instance, by rust proof 'staples engaging a fold in the bristles.

At any desired locations among the bristle' pockets 3, other pockets 5 are provided f0.1. receiving therein portions `of means Vfor .StiilV ening or supporting the bristles f 4. The stilening means, in rkthis instance, comprise 60 an elongated-member or wire (i extending to any desired distance relative tothe bristle tips and provided with upwardly turned ende 7 the extremities oi' which are imbedded inv the pockets As shown vin the drawings, 65 the bristles aremounted in orderly rows and the stiii'ening members 6 run parallel with 1 the rows and are substantiallyhidden bythe bristles. Obviously, any desired numberof stilening members may beutilized. These, v70: stilening members maintain the bristles insuhstantially their initial position atall times and effectively prevent the bristles from be-- comingset in yan oblique and distorted position which would materially detract from 7.5 the utility of; the brush. The stitfening members also aid in supporting` the bristles when the brush .is subjected-to heavy duty,.f'or instance., it used on machines or in similar places. f t g l In Figure 4 I have shown a stifeninginem;` ber 6.a provided `with upwardly turned ends 7a imbedded in relatively oblique pockets 5a, the stittening member being disposed atl an acute angle relatively to the backing member l. It is sometimes desirable to have stifening members dispo-sed at an angle to the backing member and to the bristles. It is alsol desirable, as occasion demands, to have the stiiiening members of somewhat resilient material so that they would give or bend slightly if the bristles are subjected to abnormal strain as indicated by the dotted lines in Figure 4. lt should be noted, of course, that the stiften-V ing members need not be disposed parallel to the rows of bristles but may be disposed in any desired position and at any desired angle relative to the backing member l regardless of the manner in which the bristles are mounted or disposed.

leov

Although in the present instance, the stiffening members are shown as made of Wire, it is to be clearly understood that this is merely for the purpose of clearly disclosing the present invention, and that the stifening members may be made of any desirable material, rigid or resilient. Further, it should be noted that the present invention may be embodied in any form of brush, broom, or similar device. It should also be noted that where the term bristles is used herein and in the appended claim, the same is to mean bristles, fiber, strips, or the like made of any desirable material.

From the foregoing it is apparent that I have provided a brush in which the bristles are effectively stiffened or supported' by means tending to maintain them in their initial position at all times, the means being easily mountable in a brush or the like, and affording a maximum of durability Without adding materially to the cost of manufacturing the article as a Whole, the article being very economically manufactured.

I am aware that many changes may be made and numerous details of construction may be varied through a Wide range Without departing from the principles of this invention and I, therefore, do not purpose limiting the patent granted hereon otherwise than necessitated by the prior art and as defined by the scope and spirit of the appended claim.

I claim as my invention:

As an article of manufacture, a brush including a head member having a plurality of pockets therein, bristles secured in some of said pockets, a plurality of elongated U- shaped Wires concealably disposed among said bristles of less Width than said head and arrangedtending to maintain certain of said bristles in substantially their initial position, said Wires having their end portions embedded in other of said pockets.

In testimony whereof I have hereunto subscribed my name at Jonesville, Hillsdale County, Michigan.
